Is System V IPC namespace still shared across jails?

[Mark Martinec]

Regarding installation of PostgreSQL in a FreeBSD jail, the web hold 
plenty of
warnings/advice that each postgres instance should have a unique UID, 
otherwise
they stumble across each other's feet:

| allow.sysvipc
|   A process within the jail has access to System V IPC primitives. In 
the
| current jail implementation, System V primitives share a single 
namespace
| across the host and jail environments, meaning that processes within a 
jail
| would be able to communicate with (and potentially interfere with) 
processes
| outside of the jail, and in other jails.


Is this still the case in FreeBSD 11.0 ???

I remember hearing rumors that the System V namespace
no longer is (will?) be shared across jails.
(Couldn't find it being mentioned in release notes.)
